[0029] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0030] like Figure 1As shown, in the smart riser card supporting power supply switching provided by the utility model, the full English name of the riser card is riser expansion card. SmartNIC is a smart network card.

[0031] The smart riser card of this embodiment includes: a PCB board. The PCB board is provided with a Y-shaped connector, a plurality of signal transmission lines and a plurality of PAD connection devices. The number of signal transmission lines and the number of PAD connection devices involved in the PCB board of this embodiment can be set according to the actual needs of the smart riser card.

[0032] Specifically, a first end of the signal transmission line is connected to a power supply end of the mainboard, and a second end of the signal transmission line is connected to a first PAD connection device.

[0033] For this embodiment, the smart riser card can extend the slot on the motherboard to other positions of the chassis to connect more devices. The smart riser card can be connected to the motherboard through a signal transmission line, and of course, it can also be connected to the motherboard through a slot and a gold finger to achieve signal transmission. In the process of signal transmission, the riser card plays a role in signal transmission and conversion.

[0034] This is based on the connection between the riser card and the motherboard slot, transmitting the signal from the motherboard to the riser card, and then transmitting the signal to other devices through the riser card. This signal transmission method can effectively expand the number of motherboard slots and meet users' needs for hardware expansion.

[0035] In some embodiments of the present application, the first end of the Y-shaped connector is connected to the power supply terminal of the mainboard; the second end of the Y-shaped connector is connected to the second PAD connection device; and the third end of the Y-shaped connector is connected to the power supply terminal of the mainboard external device.

[0036] It can be seen that in addition to signal transmission, the riser card can also provide power supply for the expansion device. For example, in this embodiment, the riser card is configured with multiple PAD connecting devices for connecting the power cord. In this embodiment, the power cord can be connected based on the PAD connecting device to transmit the power signal from the mainboard to the riser card, and then the power signal is transmitted to the corresponding mainboard external device. In this way, the riser card can provide a stable power supply for the mainboard external device to ensure its normal operation. The PAD connecting device in this embodiment can be a welding wire PAD, which is a metal area used for welding and connecting with other electronic component pins or mainboard external devices.

[0037] The mainboard external device involved in this embodiment may be a smart network card, a sound card, a graphics card, a memory card, and the like.

[0038] In this embodiment, the PAD connection device is connected to the PCB board by welding or plugging. When the plugging method is adopted, corresponding male and female heads can be configured to facilitate the connection.

[0039] As for this embodiment, the expansion slot on the smart riser card is powered by a PAD connection device instead of a Power Conn. By replacing the PowerConn with the PAD connection device, the space occupied by the Power Conn on the PCB board can be reduced, and the layout difficulty of various components in the limited space on the PCB board can be reduced. In addition, the power supply on the smart riser card through the welding wire is more flexible in routing.

[0040] As for this embodiment, the PAD connecting device is configured with a male head and a female head to connect to an ordinary cable or a power supply line that supports the smart network card. The other ends of these two power supply lines are then connected to the corresponding power connector on the motherboard. In this way, the power connector on the motherboard realizes the interconnection of the power signal with the PAD connecting device through the signal transmission line, and can realize the switching between the ordinary expansion slot on the riser card and the expansion slot that supports the smart network card.

[0041] According to actual needs, the PCB board is also provided with a PCI-E × 16 gold finger, which is connected to the PCI-E × 16 slot. Of course, other slots such as PCI-E × 8 slots can also be provided to meet the use requirements of the smart riser card.

[0042] In this embodiment, the PCB board is further provided with a plurality of slots, which may be PCI slots, PCI-E slots, or AGP slots. The power supply end of each slot is respectively connected to the first PAD connection device or the second PAD connection device.

[0043] Optionally, the slot is a PCI-E×16 slot, and the P3V3-STBY end of the PCI-E×16 slot is connected to the Multitrack interface of the motherboard through a gold finger. The P12V end of the PCI-E×16 slot is connected to the power supply end of the motherboard through a first PAD connection device and a first signal transmission line.

[0044] For example, Figure 2 As shown in the figure, the external device of the motherboard adopts a smart network card; the P3V3-STBY end of the PCI-E×16 slot is also connected to the P3V3-STBY end of the PCI-E×16 slot with the smart network card inserted. The P3V3 end of the PCI-E×16 slot and the P3V3 end of the PCI-E×16 slot with the smart network card inserted are respectively connected to the ISM6636B-3300 chip.

[0045] As an implementation method of the utility model, the slot is powered by a PAD connecting device on the riser card. Taking a riser card with 2 slots as an example, the first PAD connecting device can power the first PCI-E×16 slot, and the second PAD connecting device can power the other PCI-E×16 slot; one end of the PAD connecting device is welded to the riser, and the other end is welded to the female head of the power connector.

[0046] For the signal transmission line of this embodiment, the first end of the first signal transmission line can be connected to the 2×3 Power Conn on the mainboard end, and the second end is connected to the power connector female end of the PAD connection device.

[0047] In order to connect external devices to the motherboard, a Y-type connector is configured.

[0048] The first end of the second signal transmission line is connected to the 2×4 Power Conn of the mainboard, and the second end of the second signal transmission line is connected to the first end of the Y-type connector; the second end of the Y-type connector is plugged into the second PAD connection device; the third end of the Y-type connector supplies power to the smart network card.

[0049] In this embodiment, when the motherboard is connected to the riser card for communication, the 2×3 Power Conn or 2×4 Power Conn on the motherboard can be connected through the signal transmission line to realize the connection of the motherboard power supply. The PAD connection device realizes the power supply to the motherboard external device.

[0050] Optionally, multiple signal transmission lines and several PAD connecting devices are provided on the PCB board, so that the same number of slots as the PAD connecting devices can be placed to power the slots. The PAD connecting devices can be connected to the mainboard power supply for power supply, and can also power the connectors on the slots.

[0051] It can be seen that in this embodiment, Power Conn may not be used to power the riser card. Instead, a PAD connection device is configured on the riser, and two-stage power supply is provided through a signal transmission line and a PAD connection device to achieve interconnection of power signals between the riser card and the motherboard. The power supply mode of the slot on the riser card is switched by flexibly switching the type of power supply line to meet the use requirements of the riser card.

[0052] This embodiment also provides another implementation method. Specifically, it also provides a network communication device, such as Figure 3 As shown, it specifically includes: a mainboard, an intelligent network card and an intelligent riser card; the mainboard is connected to the intelligent network card through the intelligent riser card.

[0053] The riser card of the utility model can also be applied to a specific server. By optimizing the power distribution and expansion mode, the intelligent riser card improves the stability and reliability of the server, reduces the loss and interference in the power distribution process, and reduces the system failure rate caused by power problems.
